To provide a proton conductive polymer electrolyte producible at a low cost and exhibiting high proton conductivity even at a low water content to keep a sufficient strength.

The proton conductive polymer electrolyte is composed of a polymer containing a macrocyclic compound having an ionic dissociation group. The invention further provides a proton conductive polymer electrolyte membrane and a method for the production of the proton conductive polymer electrolyte membrane by applying a varnish containing the proton conductive polymer electrolyte to form a film and removing the solvent from the film.
